USE SCENARIOS
- Suitable for gas leak detection
- Because the vent is positioned outside the sound field, venting takes place through the preamplifier housing and particles in the test environment cannot enter the microphone through the vent. Some types of particles can damage the microphone by destabilising the internal charges stored in the electret
